This method has a clear advantage, pragmatism! Improvisation is not made that small stuff to know, plans, scales and arpeggios but a set of instrumental expression technology for the musical discourse. It may sound pompous words like that but actually all comes with a timed daily work. Some examples of subjects studied, the systematic alternation of played and not played steps, using different sentence lengths, playing with accents, varying the rhythmic density, rhythmic movements etc ... A true approach improvisation with of course the use of "guide-tones", scales, triads, arpeggios integrated in this process. A method 182 pages with 2 CDs for several years of work. Superb !!!
